They are a front view (A), a top view (B), and a side view (C) of the press contact 1 according to the present invention. It is a front view of the use condition of the connector 2 for pressure welding equipped with the pressure contact 1 of the same invention. It is sectional drawing along the AA line in FIG. FIG. 4 is a front view (A), a side view (B), and a front view for explanation (C) in a state of being connected to a carrier, of a pressure contact contact 11 having one pressure contact portion according to a conventional example. It is a front view (A), a top view (B), and a side view (C) of the press-connecting connector 12 according to the conventional example, wherein the press-connecting portions are arranged in a pair and face each other.

  As shown in FIG. 1-A, the press contact 1 according to the present invention is provided with a main holding portion 1a which is a second holding surface that reliably connects the contacts by reliably receiving a load during press contact. That is. Moreover, the protrusion part 1b which prevents the inclining of the press-contact part by the deformation | transformation at the time of the press injection is provided.

  As shown in FIGS. 1A and 1B, the press contact 1 according to the present invention is formed of a metal thin plate as a whole, and a press contact portion 1d in which a pair of press contact blades 1c are arranged in parallel, An insulator press-fit portion 1e extending below the press-contact portion 1d and press-fitted into the press-fit portion 2b of the housing 2a of the press-contact connector 2 (see FIG. 3), and a lower position of the insulator press-fit portion 1e And a contact portion 1f which is a contact piece protruding toward the bottom.

  Then, a bottom surface 2d (see FIG. 3) of the concave portion 2c for accommodating the contact portion in the press-connecting connector 2 (see FIG. 3) protrudes from the lower end portion of the insulator press-fitting portion 1e with an appropriate interval 1g along the contact portion 1f. A main holding portion 1a having a holding surface (bottom surface) 1aa that abuts when the press contact 1 is mounted is projected from the main contact portion 1a (see FIG. 3).

  As shown in FIG. 1-B (C), the main holding portion 1a has a U-shape that is upward when viewed from the left and right sides in a state where the pressure contact 1 is placed in the vertical direction.

  Further, a protrusion 1b for preventing inward collapse is provided on each of the inner surfaces facing in the left-right or front-rear direction of the pair of press contact portions 1d.

  The press contact 1 has a sub holding portion 1h, which is a first holding surface, below the insulator press-fit portion 1e with respect to the conventional press contact, and further extends downward from the insulator press-fit portion 1e. Thus, an upper U-shaped main holding portion 1a is provided.
